Application filed May 16, 1883. (No model.)

To aZZ whom it 711/047/ concern.: Beit known that we,W'1vI. E. GIBBS, of Elizabeth, New Jersey, an d CRAs. G. Oris, ofBrooklyn, New York, have invented certain Improvements in the Manufacture of Soap, of

which the following is a specication.

`Ourinvention consistsin certain means, fully described hereinafter, whereby We are enabled to secure a speedy and effective combination ro of the ingredients used in soap-making, and to secure a superior product at less expense than is required by ordinary processes of manufacture.

In the drawings, Figure lis asectional elevation of an apparatus devised by us for carrying out our invention. Fig. 2 is a transverse section on the line l 2, Fig. 1.

The boilermay be constructed in any suitable manner, so as to be heated either by a lurnace 2o or otherWise--as by a sand bath or hot pipes and so as to afford along heated passage which may be traversed by the materials of which the soap is to be made. In this passage or channel is` placed a mass of nails, pebbles, broken coke, or any material Whichwill break up or subdivide the stream of material as it moves along the channel, thereby effecting a thorough mixing and agitation as Well as bringing every portion into contact with the heated 3o surfaces. The result is that saponification takes place much more quickly and uniformly, with less loss and less detriment to thematerial, and results in a better product than is possible by ordinary means. l

Vhile apparatus of different constructions may be employed to carry out the above operations, We show in the drawings one which has proved effective.

J is a cylindrical boiler,of metal, supported provided with suitable lines G and uptake H. Through this boiler extends a pipe, D, bent to extend back and forth longitudinallyfthrough the boiler, and surrounded by Water, oil, sand, or other iuid or material and filled with coke s, y

pebbles, or the equivalent thereof.

A is a pump by which the fat and alkali are drawn through thefeed-pipe c from any suitable receptacle, audforced through the pipe D.

boiler, maybe carried in the form of a coil, B, through a cylindrical vessel, C, then thrugh the boiler. and then back to the vessel C, so

as to communicate with the space w, surrounding the coil, and a pipe, b, leading from said vessel, may be provided with aweighted valve,

K. This construction causes the hot saponied material to pass into the chamber as, and

to impart its heat to the coil B, and`u to the fresh material passing through the latter, which 6o is thus heated, so as to avoid the sudden elevation of temperature which would result from passing the material directly to the heated portion of the pipe, While the saponiied material is partly cooled, so that it can be more 6 5 speedily and readily brought to a solid condition after leaving the apparatus. There is also a saving of fuel resulting from utilizing the heat extracted from the saponified material in cooling it.

Apparatus differently constructed may be employed to secure the contact of the ini-lowing material with the pipes or conduits through which the outgoing material passes. Ve therefore do not linut ourselves to the precise construction and arrangement set forth.

Ve have found that by the means above described We are enabled with a temperature of about 350 Fahrenheit to completely saponify ordinary mixturespf fat and alkali as fast as the material traverses the pipes and passages, the mixture entering at one end of the machine and a constant stream of soap leaving the other. Ve have also found that the product is superior, and that the materials are better combined. I

Ve do not abandon or dedicate to the public any patentable features set forth herein and not hereinafter claimed, but reserve the right to claim the same either ina reissue of any patent that may be granted upon this application or .in other applications for Letters-Pat` ent that We may make.

XVe therefore claiml. As an improvement in the art of soapmaking, passing the mixture of alkali and fat forcibly through a heated channel filled with small particles of iron or other substance, substantially as set forth. Y
